RooFlNG-PLATE.

SPECIFICATION forming part of Letters Patent No.'322,990, dated July 28, 1885. Application filed April 9.7, 1885. (No model.) Patented in England April 13, 1885, No. 4,539.

To all whom, t may concern:

Be it known that we, JOSEF SPORNY and IAN ZARsKr, both subjects of the Emperor of Russia, residing at the city of Varsaw, in the Empire of Russia, have invented certain new and useful Improvements in Roofingllates, of which the following is a specication.

This invention has reference to a'n improved roofing plate or shingle made of veneers united at cross-grain; and the invention consists of a roong-plate formed of layers of veneers united at cross-grains to each other and coated at the outer surface with a layer of asphaltum and small stones and at the under side with soluble glass.

In the accompanying drawings, Figure l represents a vertical transverse section of a roof made of our improved roofing-plates. Figs. 2 and 3 are side elevations of aroof, showing different arrangemcnts of the roofing plates. Fig. 4. is a vertical transverse section through the roofing-plates; Fig. 5, a vertical longitudinal section of the same, and Figs. 6 and 7are respectively a plan and a vertical section of a roofing-plate drawn on Va'larger scale.

Similar letters of referenceindicate.corresponding parts.

The roofing-plates that form our improved rcof-covering are made of from two to ve layers of veneers that are arranged at crossgrains to each other, and united by means of a suitable cement in such amanner that the rocngplate can resist the influences of the atmosphere, moisture, and rain.y

The roofing-plate A is made of any suitable size and of square, oblong, or other shape. To impart a high degree of durability to the same, the roofngvplates are soaked in tar or suitable bituminous substances to render them Water-proof. They are coated at their outer surface with a layer of asphaltum, int-o which are pressed, while soft, small pebbles or stones, while the under side of the platesns coated with soluble glass or any other approved substance, whereby both sides are rendered fireproof.

The roofing-plates `can be attached to the roof in differegt modes. In Fig. 2the roofingplates are arranged diagonally'to the. rafters, while in Fig. 8 they are arranged parallel to the rafters. In Figs. 5 and 7 the plates are shown with recessed edges, so as 'to facilitate the overlapping of the plates. The recessed edges, however, may be dispensed with.

The advantages of our improved roongplates are, that the roofs do not require to be boarded, but that the plates can`be put down directly cn the rafters.

The roof-covering is cheap, light, and durable, and has a high degree of resistance to atmospheric influences. It can be used with any slope of roof and distance between the rafters.

Having thus described our invention, we claim as new and desire to secure by Letters Patent* A roong-plate consisting of two'or more veneers arranged at cross-grain to each other, f

and coated at the outer surface with asphaltum and broke-n stones, and at the under side with soluble glass or otherfire-pnoof substance,sub stantially as set forth.

In testimony whereof we have signed our names to this specication in the presence of two subscribing witnesses.
